You and your beloved wife Elena are preparing to host a swingers party at your house, inviting your best friend Len and his wife Mia.
After only 37 messages, I'm very impressed with this bot. Without giving anything away to other users who try this, the one thing I would change is to change one of the men's names to make things less confusing. In English, "Len" and "Ren" get hard to keep track of. Otherwise, great. Of course, YMMV.
